The *Max Planck Institute for Neurological Research* with Klaus-Joachim-Zülch-Laboratories of the Max Planck Society and the Faculty of Medicine of the University of Cologne is seeking applications for a cooperation consisting of a small group of researchers under the supervision of Dr. Marc Tittgemeyer and Prof. Dr. Klaas Enno Stephan within the context of the newly established transregional collaborative research centre TR-CRC 134 (“Ingestive Behaviour: Homeostasis & Reward”, Cologne/Lübeck/Hamburg): *Postdoctoral Position for a Computational/Systems Neuroscientist* The project “Investigating hormonal modulation of dopaminergic mechanisms underlying impulsivity” combines computational modelling techniques with human neuroimaging and behavioural investigations, with the goal of obtaining quantitative in vivo markers of dopaminergic transmission and its modulation by hormones. We are searching for enthusiastic candidates with a strong interest in computational neuroscience and/or systems neuroscience. The ideal candidate is a physicist, engineer or computer scientist with a strong background in computational modelling techniques of human neuroimaging data. He/she will be responsible for the methodological part of the project, including modelling and statistical data analysis. Prior experience in fMRI and computational modelling is required. Furthermore, candidates are expected to have solid programming skills (particularly in Matlab). Finally, because of the inter-regional nature of this collaborative project, the position involves regular collaboration meetings and work stays outside Cologne. A certain degree of flexibility with respect to travelling is therefore expected. The position is available from April 1st 2014, initially for 2 years with the possibility of extension for a further 2 years. The institute provides an excellent multi-disciplinary and interactive research environment with a research-dedicated 3T MRI scanner, PET and EEG facilities, and behavioural labs. Interested candidates should submit their application as a single PDF document (including CV, publication list, contact details of two references and a short statement of research interests) via email. To apply or for further information please contact: Max-Planck-Institut für neurologische Forschung Verwaltung Gleueler Str. 50 50931 Köln personal(a)nf.mpg.de Review of applications will start immediately and will continue until the position is filled.
